We will do our best to process any cancellation or change requests before your order is sent to our warehouse. However, Tubemount.com cannot guarantee that any order can be changed or canceled after the order has been placed. If the order has been shipped, or for some other reason we are unable to cancel or modify the order, the customer will be responsible for the full cost associated with shipping the product back to us, as well as the 20% restocking fee mentioned above. Please order carefully, and if you’d like to cancel, contact us as soon as possible.
